A geographical systems analysis of the commercial crawfish industry in south Louisiana

Creator:: Gary, Don L
Abstract:: The crawfish enterprise of South Louisiana is shown to haveexpanded as much as 18-fold since the 1950's. It is estimated(1973) that there are about 44,000 acres of managed crawfish ponds.Of the 334 ponds identified and mapped in the thesis, 231 are classedas open ponds, 45 as rice field ponds, and...

Effect of sheep grazing on subterranean clover (Trifolium subterraneum L.) seed production

Creator:: Steiner, Jeffrey John
Abstract:: Subterranean clover (Trifolium subterraneum L.) seed production practices in Oregon are different from those in Australia. There, seed is produced on fields which are managed primarily for forage. In Oregon, seed fields are managed for seed as the primary product and forage is of secondary concern. Some sheep grazing is...

Effect of moisture stress on yield and quality of winter wheat seed

Creator:: Assuncao, Marcos Vinicius
Abstract:: Two experiments were conducted to determine the effects of moisture stress on physiological changes that occur during the vegetative and reproductive stages of the wheat (Triticum aestivum L.) plant, and to relate these effects to seed yield, quality and performance. In a field experiment, different levels of moisture stress were...

Utilization of the night-interruption phenomenon to hasten the seed increase of long-day cereals during short-day regimes in California and Arizona

Creator:: Ebeltoft, David C.
Abstract:: Tests were carried on in growth chambers and in the field to determine if the harvest of daylength-sensitive long-day cereals grown during the winter in Arizona could be hastened 30 days by the use of night interruption. Two durum lines which were near-isogenic for sensitivity to daylength were used throughout...

Temperature preconditioning of ryegrass (Lolium sp.) seed dormancy

Creator:: Wiesner, Loren E.
Abstract:: The purposes of this study were to determine the effects of temperature, nutrients, growth regulators, and culm detachment during seed development on ryegrass seed dormancy and weight. The effects of storage temperature on seed dormancy were also studied. Seed dormancy of annual (Lolium multiflorum Lam.) and perennial (Lolium perenne L.)...

Endosperm morphogenesis in wheat (Triticum aestivum L.)

Creator:: Huber, Andrew Gail, 1944-
Abstract:: Wheat endosperm morphogenesis was studied by light microscopy during the entire growth period of anthesis to maturity. Four developmental stages have been described in this thesis: (1) double fertilization, (2) formation of the lower endosperm cells, (3) termination of nuclear divisions, and (4) initiation of protein bodies. The first manuscript...

Spring establishment of orchardgrass and tall fescue seed crops with cereal companion crops

Creator:: Chastain, Thomas G.
Abstract:: Orchardgrass and tall fescue seed crops are commonly springplanted in Oregon, but do not produce a marketable crop during the first growing season. Establishing orchardgrass and tall fescue with cereal companion crops would provide income during the seeding year and could increase seed production profits. This study was conducted to...
